Description

Technical Field

[0001] This utility model belongs to the field of crankshaft technology, specifically relating to a crankshaft with a protective structure. Background Technology

[0002] The crankshaft is the most important component in an engine. It bears the force transmitted from the connecting rod and converts it into torque, which is then output through the crankshaft to drive other accessories on the engine. The crankshaft is subjected to the combined effects of centrifugal force from the rotating mass, periodically changing gas inertial force, and reciprocating inertial force, resulting in bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the journal surfaces must be wear-resistant, operate evenly, and have good balance.

[0003] Existing crankshafts still have some defects. Most of the components are fixed by welding, which can easily lead to weld seams after prolonged use, resulting in insufficient stability. Furthermore, if one part is damaged, the entire crankshaft needs to be replaced, increasing the cost of use. Therefore, we propose a crankshaft with a protective structure. Utility Model Content

[0004] The purpose of this invention is to provide a crankshaft with a protective structure to solve the problems mentioned in the background art, such as insufficient stability and high cost due to welding and fixing of various components.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crankshaft with a protective structure, comprising a mounting plate and a fixed shaft. A fixed shaft is provided on one side of the mounting plate, and the fixed shaft is fixedly connected to the mounting plate. A fixed plate is provided at one end of the fixed shaft. A mounting block is provided on one side of the fixed plate, and the mounting block is fixedly connected to the fixed plate. A insertion rod is provided in the middle of the mounting block, and the insertion rod is movably connected to the mounting block. A limiting plate is provided in the middle of the insertion rod, and the limiting plate is fixedly connected to the insertion rod. A spring is sleeved on the surface of the insertion rod. A insertion hole is embedded at one end of the fixed shaft, and the insertion rod and the insertion hole are fixed by interlocking.

[0006] Preferably, a bolt is provided on one side of the fixing plate, and a through hole is provided on one side of the fixing plate, and the bolt and the through hole are fixed by insertion.

[0007] Preferably, the surface of the fixed shaft is provided with a threaded hole, and the bolt and the threaded hole are connected by threads.

[0008] Preferably, a limiting block is provided on one side of the fixed shaft, and a limiting groove is embedded in the inner wall of the fixed plate, wherein the limiting block and the limiting groove are slidably connected.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4This utility model provides a technical solution: a crankshaft with a protective structure, including a mounting plate 1 and a fixed shaft 2. The fixed shaft 2 is provided on one side of the mounting plate 1, and the fixed shaft 2 is fixedly connected to the mounting plate 1. A fixed plate 3 is provided at one end of the fixed shaft 2. A mounting block 4 is provided on one side of the fixed plate 3, and the mounting block 4 is fixedly connected to the fixed plate 3. A plug rod 5 is provided in the middle of the mounting block 4, and the plug rod 5 is movably connected to the mounting block 4. A limiting plate 6 is provided in the middle of the plug rod 5, and the limiting plate 6 is fixedly connected to the plug rod 5. A spring 7 is sleeved on the surface of the plug rod 5. A plug hole 8 is embedded at one end of the fixed shaft 2. The plug rod 5 and the plug hole 8 are fixed by insertion. The mounting block 4, the plug rod 5, the limiting plate 6, the spring 7, and the plug hole 8 are provided to achieve the fixation between the mounting plate 1, the fixed shaft 2, and the fixed plate 3. It is only necessary to insert the fixed shaft 2 into the interior of the fixed plate 3 and insert the plug rod 5 into the interior of the plug hole 8 to achieve fixation. No welding fixation is required, which effectively improves stability. Moreover, if one of the components is damaged, it is easy to replace it, reducing the cost of use.

[0017] Specifically, a bolt 9 is provided on one side of the fixing plate 3, and a through hole 10 is provided on one side of the fixing plate 3. The bolt 9 and the through hole 10 are fixed by interlocking. The bolt 9 and the through hole 10 provide secondary fixation between the fixing shaft 2 and the fixing plate 3.

[0018] Specifically, the surface of the fixed shaft 2 is provided with a threaded hole 11. The bolt 9 and the threaded hole 11 are connected by threads. By screwing the bolt 9 into the threaded hole 11, secondary fixation can be achieved.

[0019] Specifically, a limiting block 12 is provided on one side of the fixed shaft 2, and a limiting groove 13 is embedded in the inner wall of the fixed plate 3. The limiting block 12 and the limiting groove 13 are slidably connected. Through the provided limiting block 12 and limiting groove 13, the fixed shaft 2 can be limited, which effectively improves the stability.

[0020] Specifically, one end of the insertion rod 5 is provided with an adjusting block 14, and one end of the mounting plate 1 is provided with a mounting shaft 15.
